To all whom it may concern:

Be it known that 1, EDWARD Semen, Jr., a citizen of the United States, and. aresident of Boston, in the county of Suffolk and State of Massachusetts, have made a. new and useful Invention in Fluid-Translating Devices, of which the following is a specification.

This invention relates to fluid translating devices and particularly to devices employinge stream of liquid tor mechanically entraimng and removing an and other nonu eonclensoble gases.

vAn object of my invention is to produce a fluid translating device employing a jet of liquicl which is capable of condensing condensable fluids and of entraining noncomlensable fluids.

A further object is to produce a high speed pump or fluid translating device cspable of operating in conjunction with a condenser and of elliciently maintaining high vacuum in the condenser A further object is to produce a iiuirl translating device or pump in which it jet of liquid, for example water, is emplo 'erl-in entraining and ejecting air and other non condensable gases and which may be E111- ployecl for producing and nmintaining a high vacuum or for delivering air or other non-oondenseble gases from a low to a higher pressure.

These and other objects 1 attain in a con- (lenser' embodying the features herein clescriborl, and illustrated in the drawings :xC- oompenying this application and forming apart thereof.

In the drawings: Figure 1' longitudinal sectional view of a device embodying ill} invention; Fig. 2 is a sectional View on the line of Fig. 1; and Fig. 3 is :1 developed section of a portion ol an annular row of hlmles whi 'h form :1 rlemil of my invention.

Referring now to the drawings by inuiier- :ils of reference, 10 designates n casing pro" \lLlLll with :1 water inlet 11, on air inlet 12, and a water :mll :iir discharge port 13.

14 n shaft extending through the (Kill walls of the easing 10 and it mounted in bearings 15 and 18. Within the casing l() and fixed to the shaft ll is a pump inipeller l7 mlnpteil to force water from the inlet 11 through the annular port 18 and then through an outlet 19 in line with the pump. 21 is elistri outer shown as a Wheel, carried by the shaft 14, seicl Wheel having an annular row of blades 22 right angles to the Web thereof and in line with the outlet it and the collector cone 29. These blades are illustrated as being integral with the wheel but it is obvious that they may be secured thereto in any Well known manner,

it is r: ll known that e stream comprising size-session of thin leaves or films of Water is more elieotive in entreining and ejecting non-condensahle gases then a solid stream or strezir composed of a mess of separate drops. i therefore so construct the 22 the Wheel 20 that they will segregate the strewn of delivered through the port 15 into stream of: sueoessire leaves or fihns of water which is projected edielly, of the wheel by the velocity atteinell due to the -gressure head img'orted it the iinjiellor 17. These Segre gated films or leaves troin the blades to the collector cone 1Z0 rant-ruining hetween their: lilius of air i'r rs he air space 23, he air and water losing discharged to atmosphere.

in practising: my inrention l nzay segregate the leaves without in ting ailditionsl energy thereto, although in some cases it may he desirable to import additional radial velocity to them by nae-ins of the l have illustruterl the wheel eonstrurlerl that the writer will through port 1 and blades K .Yhirh corresponds to the differishsohllo pressure between the preslho entrance to the riolleotor eone Q0 and that ;.l the port it. For example, by mo ns oi the line 24- l have inrlies'terl the velocity oi the water while the line 25 lll- (limit-s the rolorily' ol' the wheel. The resultzm'l of these two rrlocities is indicated (he line 2*). ll will therefore that the hhulrs ontluwhorl lllilYfilll so dosigg'uell that the \guler will he rouolrrrl lay the wheel wilhwit iangnuyl-Enul will simply slirlo through the spaces between the hlz: ,les and (continue in the direction of its original lrnrel. by rirlue oi its original velocity after living; alirirleil into llai'n leaves. in tool the hlmles ere preferably so arranged on the wheel that l y simply art as a sliver for the stream oi outer or llll llltl delivered ence in sure at ho apparent through the discharge passage 19, and the blades maybe so designed that the separate sheets or pistons of liquid, cut oil by the inner edges of the blades, will pass through the spaces between'the blades without t0ucl1- ing the blades. It will also be apparent that instead of the blades shown, a construction of wheel may be employed to impart velocity to the stream as it leaves the port if). It will he observed that the water passes through the air entraining wheel and the impeller 17 in. series and that the wheel aiid impeller are on the same shaft and Within the same case so that a compact device is provided.

When the device illustrated is used in connection with a condenser, the port 12 will communicate with the air delivery port of the condenser, a suitable Water connection being also provided for the inlet port 11. It will be understood, that the water leaving the blades is received by the'l collecting cone 20, Where .he initial compression of the non-condensable vapor begins, it then enters the diffuser 2? where its velocity energy is gradually transformed into pressure, and it is finally discharged from the ditt'user at atmospheric pressure.

Having thus described my invention, what I claim is:

1. An apparatus of the character described, comprising a casing having a liquid inlet port, afluid inlet port, and a combined fluid and liquid discharge port, a pump Within the casing for, imparting a high velocity to the liquid entering through the liquid inlet port, the outlet of said pump communicating with the fluid inlet port, rotatable means for breaking up the stream of liquid delivered by the pump into a saccession of relatively thin leaves, and means for receiving the stream of leaves so formed and for converting the velocity energy of the liquid into pressure energy and for discharging the liquid from the casing.

2. An apparatus of the character described, comprising a casing having a liquid inlet port, a. fluid inlet porhanzl a single fluid and liquid discharge port, a pump receiving liquid from the liquid inlet port,

and having a discharge port located within the casing and incommunieation with the,

fluid inletport, a bladed Wheel located within the casing between the discharge ,port tliereor and the discharge port of the pump for breaking up the stream of liquid discharged rroin the pump into a stream of relatively thin leaves, and a combining tube and a diffuser communicating with the dis charge port of the casing for receiving the stream of relatively thin leaves issuing from said bladed Wheel.

3. In a fluid translating device, a casing having an inlet and an outlet a pump Wltl1- in a fluid translating device, a casing ha vino; an inlet and an outlet, means in the casing for imparting a high velocity to the water entering the inlet. and means adjacent the outlet for segregating the water into films or layers.

having an inlet, and an outlet means for imparting velocit to water Within the casing,

and a wheel adjacent the outlet for segregating the water into films or layers Witheel" C. In a fluid translating device, casing out imparting additional velocity thereto.-

in testimony whereof, 1 have hereunto 4' suloscribed my name this twenty-sixth clay of July 1913. 1 anwaan enliven, as.
